Application filed February 11, 1913. Serial No. 747,849.

To all whom t may concern.' l

Be it known that I, WILLIAM IV. WILSON, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to oil burners for producing heat' for industrial or domestic purposes, and more particularly for producing the high heats required for furnaces and the like and for the generation of steam for power. In such a burner, using mineral oils, the essential result to be obtained 1s the complete combustion of the oil, eliminating the fuel losses attendant upon incomplete combustion, and the production of smoke and smut and other carbonaceous by-products. Perfect combustion is of course productive of the highest degree of heatr In accordance with the present invention, the oil is introduced to the combustion chamber with a certain quantity of air which produces an initial or partial combustion sufficient to break up the oil globules so as to produce avapor which, upon the addition of further supply of air, will be capable of complete combustion in a clean blue flame devoid of smut or smoke.

Other .features are provided augmenting the combustion and contributin to the support of the complete combustion obtained in practising the invention, all as herelnafter pointed out.

The invention has for further objects the provision of improvements in oil burners which will be superior in point of relative simplicity and inexpensiveness in conjunction with positiveness of operation, completeness of combustion and economy of fuel with relation to the heat produced; and which will be of long life and capable of long continued service without deterioration or the requirement of repair or substitution of parts.

`With the above and other objects in view, the invention consists in the novel and useful provision, formation, construction, relative arrangement and combination of parts and features, all as hereinafter described, shown in the drawing and finally pointed out in claims.

In the drawing: Figure l is a vertical central sectional view of an oil burner conl structed and organized in accordance with the invention; l1g.v2 1s a vertical trans I acters.

Referring with particularity to the drawing, the improved oil burner therein shown comprises a combustion chamber .A which is in turn surrounded by an air chamber B the walls of which are joined and held in proper relation by head plate C through which passes an'oil feed member D provided at its inner end with a combined deflector and valve d disposed within the combustion chamber A adjacent to one end thereof.

Coming down to the particular construction and organization of the improved oil burner, the combustion chamber is provided with an inner wallv portion 4 of fire-brick or the like, annular in shape, and in turn confined by an annular shell 5 open at one end and adjacent to the other end provided with a head plate 6, the shell 5 at its extreme end being bolted to the head plate C, as at 7.

Openings 8 are produced through the shell 5 between the head plates 6 and C; and a central opening is formed through the head plate 6 to receive a tube 9 through which the oil feed member D ranges, with the combined deliector and valve d thereof. at the inner end of such tube, which latter projects somewhat into the combustion chamber A. Clearance is provided in the tube 9 around the oil feedmember to permit air to pass to the combustion chamber from the space between the head plates 6 and C, Such air flowing to such space through the openings 8 from the airchamber B. An annular shell l0 surrounds the annular shell 5, being spaced therefrom to produce the air chamber B, and being provided with an air inlet port 11. An air supply pipe leads to the port 1l, and air may thereby be fed to the air chamber B under pressure, mixed with steam or otherwise as preferred or most suitable. One end of the shell 10 is partially contracted and 'terminates in anr produced through the lining l of the 'combustion chamber., lin an annular series, each communicating at one end with the air chamber B through the annular space 13 and at the other end with the interior of the combustion chamber, said ports ranging obliquely away from the combined deliector and valve cl of the oil feed member D. rlhe other end of the shell l() is bolted to the head. plate C, as at lll.

The oil feed member D comprises a tubular body l5 held in the head plate C by a suitable bushina i6, and provided enteriorly'thereof with. an elbow l? whereby it is jointed to an oil feed pipe itl. vThe delector and valve a?, which acts likewise as a valve for regulating the tloiv or discharge' of oil Within the combustion chamber, is mounted at the inner end of a stem l@ which ranges through the tubular body l5 from end to end and passesout therefrom at the union or elbow l?, beingprovided at that end with a hand Wheel 20, and being threaded in the union so that by manipulation of the hand Wheel the valve al may be adjusted with respect to 'the end of the tubular body l5 which is enlarged at its outer portion to form a seat 2l for the valve d, such seat having inner and outer angularl y related faces 2l@ and 2lb which are matched with similarly formed faces upon the valve d', so 'that when the valve is entirely seatel iiovv of oil from the tubular member the valve is entirely checked. 'When the valve is slightly unseated by turning thehand Wheel 20, an annular discharge openingis formed between the valve its seat 2l, through which oil is jetted or discharged in a thin annular sheet into the combustion chamber at the end of the tube 9, -which end projects Within the combustion chamber. means of the hand Wheel 20 the amount of oil fed to the combustion chamber may be accurately and delicately regulated. The extreme terminal portion of 'the valve d is rounded od so as to `permit unobstructed mixing of the air and oil at the end of the oil feed member, such initial admixture being that of the oil and the air passed to the combustion chamber through the tube 9 from the air space between the head plates f3 and C in communication with the air chamber B. Partial combustion is supported in the immediate zone of the head d at the inner end of the combustion chamber, breaking up the globules of oil so that a finely divided or vaporized fuel, but partly burned, passes forwardly in the combustion chamber to the zone entered by the air ports Illia. Air rushingl through these ports commingles with the highly combustible fuel in that portion of the combustion chamber, producing a perfect mixture the complete and final combustion of which is supported in a long flame or jet which streams from the outer ais/agree end of the combustion chamber in the direction denoted by the arrow in Fig. l, and is thence directed as occasion requires for heating purposes. lt .is evident that the flange l0a may be projected Within the mouth of a furnace or other structure or apparatus and held therein so that the burner may be caused to apply its heat tothe objects or apparatus served by the furnace.

The combustion chamber lining Llis eventually raised to a high heat, which insures combustion of every fragment of fuel introduced to the combustion chamber; and the arrangement of the combustion chamber Within the air chamber causes a pre-heating of the air supplied to the combustion charnber which is beneficial for the production of a quick-burning mixture of air and oil vapor. Likewise, the oil during its passage through the tubular body l5, is pre-heated with the same benehcial result, by the heated air surrounding the oil feed member in the tube 9 and between the head plates e and C, lt will be understood that the space between thehead plate 6 and the head plate C constitutes a part t of the air chamber B.

lt is manifest that l may malte vmany changes and modifications, in construction and inter-relation of parts and features `in adapting the improvements to varying conditions of use and service, Without departing from the spirit of the invention or the terms of the following claims; and .l therefore reserve the right to all suchv modifications and variations as come Within the fair 10o spirit of the invention, Without attempting in `Whole or in part to disclose or outline the same.

l-laving thus described my invention, l claim and desire to secure by Letters latent: lea
